What this agent actually does
Missed calls cost service businesses real money - high-ticket categories lose hundreds of dollars on every dropped call. After-hours calls usually go to voicemail and never come back. Vox is the AI voice receptionist that picks up every call, sounds like a human, and books real appointments to your calendar.
Vox handles inbound calls 24/7. It greets callers in your brand voice, answers common questions, books appointments by checking your calendar live, modifies or cancels reservations, sends SMS confirmations, and routes anything urgent to your team. Callers get a fast helpful experience even at 2am on a Sunday.
Your front desk stops being a bottleneck. Your evenings and weekends stop costing you bookings.
